Member Function Documentation

add_element()

void turi::groupby_operators::argmax::add_element ( const std::vector< flexible_type > &  values )

inlinevirtual

Adds an element to the aggregate. Elements to be added will be either the input_type (as set by set_input_type()) or UNDEFINED.

Operator that expects more than one input values need to overwrite this function

Reimplemented from turi::group_aggregate_value.

Definition at line 366 of file groupby_aggregate_operators.hpp.

partial_finalize()

virtual void turi::group_aggregate_value::partial_finalize ( )

inlinevirtualinherited

No more elements will be added to this value. However, this value may still be combined with other values.

Reimplemented in turi::groupby_operators::quantile.

Definition at line 75 of file group_aggregate_value.hpp.

print()

virtual void turi::group_aggregate_value::print ( std::ostream &  os ) const

inlinevirtualinherited

Override this function for allowing the operator to be easily printed.

std::cout << aggregator <<s std::endl;

Reimplemented in turi::groupby_operators::variance.

Definition at line 134 of file group_aggregate_value.hpp.
